What has a Finnish-made film about illegal immigrants in France got to do with a renowned evolutionary theorist? Or the Guardian? The film in question is Le Havre, by Aki Kaurismäki, a gentle yet robustly political parable set in the French coastal town of the title, with a similar tone to a previous film, The Man Without A Past. Pagel, meanwhile, is an evolutionary theorist who operates on every scale, from genetic codes to language, culture and the history of human co-operation. That gives you a clue to his take on the movie, but the post-screening discussion could lead anywhere, especially since you can watch the film on the Guardian website, submit questions, read the live blog and watch the film any time in the next two months.

This is the type of festival that the Easter holidays were made for, and it manages to cover all bases. For the very young, there's the Octonauts on the big screen, with added treasure hunt. In the middle, there's a selection of quality international children's movies and animation from Michel Ocelot's gorgeous Tales Of The Night to Spain's Morph-like Capelito The Magic Mushroom. Teens will go wild for the twisty The Cabin In The Woods by Buffy The Vampire Slayer creator Joss Whedon. Parents can relive their youth with retro fare Labyrinth and Oliver! And hearts of all ages will melt with the uplifting Muppet documentary Being Elmo: A Puppeteer's Journey.

The complaint that women are underrepresented across the film industry in the UK is likely to hold up for decades to come, but there's surely never been a better time for role models. This season reminds us of how far we've come just in the past decade, and how many of Britain's brightest film-making talents are women. Andrea Arnold, Lynne Ramsay, Joanna Hogg, Carol Morley, Lucy Walker, Clio Barnard – they've taken British film to the Oscars, Cannes and everywhere else, and more importantly, they've produced some of the defining films of the era, from Morvern Callar to Fish Tank, Dreams Of A Life to Unrelated, all of which feature in this season. That's surely progress?

What better place to mark the centenary of the almighty maritime disaster than the Belfast docks from which the ill-fated liner was launched? And don't say, "on the sofa watching Julian Fellowes's TV version." Beside the Titanic dry docks there are screenings of the Titanic-themed 1958 classic A Night To Remember (Mon) and the new Irish-made Saving The Titanic, which focuses on the heroic engineers (Tue). And that's just the tip of the … er, sorry. And next week there's a Titanic-related pop-up cinema at Belfast City Hall. In London, meanwhile, the BFI presents Titanic movies from EA Dupont's 1929 obscurity Atlantic to a troubled Nazi propaganda version, and Hitchcock's attempt to film the story in Hollywood – which unfortunately ended up meeting a similar fate to the ship itself. Not to mention James Cameron's recent, glitzy, 3D-ified Titanic, at the BFI IMAX and elsewhere.
